Description

Technical Field

[0001] This application relates to the field of electronic devices, specifically to a pair of headphones and a wearable electronic device. Background Technology

[0002] Clip-on headphones are a type of open-back headphone that is worn by clipping onto the user's ear and transmits sound through an open acoustic design.

[0003] Clip-on headphones typically have a sound-producing part, a first clamping part connected to the sound-producing part, and a second clamping part rotatably connected to the first clamping part. When wearing the headphones, the user can rotate either the first or second clamping part to clamp the ear between the first and second clamping parts to secure the headphones. At this time, the first clamping part is located in front of the ear, and the second clamping part is located behind the ear. However, the second clamping part may press against the base of the user's ear, causing discomfort. Utility Model Content

[0004] This application provides an earphone and a wearable electronic device that can prevent the second clamping part from pressing against the base of the user's ear, thereby improving the user experience.

[0005] In a first aspect, embodiments of this application provide an earphone, including: a sound-emitting part, a first clamping part, and a second clamping part. The sound-emitting part is a rotating body and has a sound outlet hole. The first clamping part is connected to the sound-emitting part, and the second clamping part is rotatably connected to the first clamping part. When the first clamping part and the second clamping part are rotated relative to each other to a wearing state, the first clamping part and the second clamping part are both located on the same side of the rotation axis of the sound-emitting part, and there is a gap between the second clamping part and the rotation axis of the sound-emitting part in a first direction perpendicular to the rotation axis of the sound-emitting part.

[0006] With the above configuration, when a user wears the headphones, at least part of the sound-producing part is located inside the user's ear canal. The first clamping part and the second clamping part are located on both sides of the user's auricle. Since there is a gap between the rotation axis of the second clamping part and the sound-producing part, the second clamping part is far away from the root of the user's ear, which can prevent the second clamping part from hitting the root of the user's ear and improve the user experience.

[0007] Optionally, when the first clamping part and the second clamping part are rotated relative to each other to the wearing state, in the first direction, the distance between the rotation axis of the second clamping part and the sound-emitting part is between 2mm and 4mm.

[0008] With the above settings, when the user wears the headphones, the second clamping part can be prevented from pressing against the base of the user's ear, thus improving the user experience.

[0009] Optionally, both the first clamping part and the second clamping part are arc-shaped, and the radius of the circle containing the first clamping part is equal to the radius of the circle containing the second clamping part. When the first clamping part and the second clamping part rotate relative to each other to the storage state, the first clamping part and the second clamping part together form a partial arc of a circle.

[0010] With the above settings, when the earphones are stored on the main body of the device, the earphones can match the shape of the main body of the device, improving the visual effect of wearable electronic devices.

[0011] Optionally, the arc length of the first clamping part is greater than the arc length of the second clamping part. With this configuration, when the user wears the headphones, the second clamping part can be prevented from pressing against the base of the user's ear, thus improving the user experience.

[0012] Optionally, the sound-emitting part is disposed at the first end of the first clamping part, the second end of the first clamping part is rotatably connected to the first end of the second clamping part, the second end of the second clamping part is a free end, the distance between the rotation axis of the first clamping part and the second clamping part and the first end of the first clamping part is a first distance, the distance between the rotation axis of the first clamping part and the second clamping part and the second end of the second clamping part is a second distance, and the first distance is greater than the second distance.

[0013] With the above settings, when the user wears the headphones, the second clamping part can be prevented from pressing against the base of the user's ear, thus improving the user experience.

[0014] Optionally, the sound-generating part has a first end face and a second end face that are arranged opposite to each other along its own axis of rotation. The second end face is closer to the second end of the first clamping part than the first end face. The sound-generating part is provided with an anti-slip groove that surrounds the circumferential sidewall of the sound-generating part. The anti-slip groove is closer to the first end face than the second end face.

[0015] With the above design, the anti-slip grooves can prevent the sound-producing part from sliding between the user's fingers, making it easier for the user to pick up the headphones.

[0016] Optionally, the first clamping part is connected to the circumferential sidewall of the sound-emitting part, and in the first direction, the sound outlet and the first clamping part are respectively disposed on both sides of the sound-emitting part, and the sound outlet is closer to the second end face than the first end face.

[0017] With the above settings, when the headphones are worn on the user's ear, the sound outlet can face into the user's ear canal, improving the sound reception effect.

[0018] Optionally, the headphones also include a human body sensing unit located inside the earphone housing and in contact with the inner wall of the housing. The human body sensing unit is configured to generate an electrical signal based on changes in capacitance on the outer surface of the housing to detect whether the user is touching the headphones.

[0019] With the above settings, the human body sensing unit can detect whether the user is wearing headphones.

[0020] Optionally, multiple human body sensing units are used, with each unit located within the sound-emitting part and the first clamping part. This configuration allows the human body sensing units to accurately detect whether the user is wearing headphones.

[0021] Secondly, embodiments of this application provide a wearable electronic device, including: a device body, a strap connected to the device body, and an earphone in any of the above embodiments, wherein the earphone is housed in the device body.

[0022] With the above configuration, the strap can wrap around the user's wrist, ankle, or upper arm to wear the device. The user can then remove the earphones from the device and put them on. When the user wears the earphones, at least part of the sound-producing part is located inside the user's ear canal. The first and second clamping parts are located on either side of the user's auricle. Because there is a gap between the rotation axis of the second clamping part and the sound-producing part, the second clamping part is far from the root of the user's ear, which avoids the second clamping part pressing against the root of the user's ear, thus improving the user experience.

[0023] The earphones provided in this application embodiment have a rotating sound-emitting part with a sound outlet. A first clamping part is connected to the sound-emitting part, and a second clamping part is rotatably connected to the first clamping part. When the first and second clamping parts are rotated relative to each other to the wearing state, both the first and second clamping parts are located on the same side of the rotation axis of the sound-emitting part, and there is a gap between the second clamping part and the rotation axis of the sound-emitting part in a first direction perpendicular to the rotation axis of the sound-emitting part. When the user wears the earphones, at least part of the sound-emitting part is located inside the user's ear canal, and the first and second clamping parts are located on both sides of the user's auricle. Because there is a gap between the second clamping part and the rotation axis of the sound-emitting part, the second clamping part is far from the root of the user's ear, which can prevent the second clamping part from pressing against the root of the user's ear and improve the user experience.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all possible embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0042] As used herein, terms such as “equal,” “parallel,” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equal items less than or equal to 5% of either one.

[0043] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0044] This application provides an earphone 30. The sound-emitting part 100 of the earphone 30 is a rotating body. A first clamping part 200 is connected to the sound-emitting part 100, and a second clamping part 300 is rotatably connected to the first clamping part 200. When the first clamping part 200 and the second clamping part 300 are rotated relative to each other to a wearing state, both the first clamping part 200 and the second clamping part 300 are located on the same side of the rotation axis of the sound-emitting part 100, and there is a gap between the second clamping part 300 and the rotation axis of the sound-emitting part 100 in a first direction x perpendicular to the rotation axis of the sound-emitting part 100. Therefore, when a user wears the earphone 30, the second clamping part 300 can be prevented from pressing against the root of the user's ear 2, thus improving the user experience.

[0045] Please refer to Figure 1 This application provides a wearable electronic device 1, which may include a smartwatch, a sports watch, a smart bracelet, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, etc. This application does not limit the type or wearing location of the wearable electronic device 1. The following embodiments of this application will use a smartwatch as an example to describe the wearable electronic device 1. It should be understood that the wearable electronic device 1 in this application is not limited to a smartwatch.

[0046] The wearable electronic device 1 includes a main body 10 and a strap 20 connected to the main body 10. The main body 10 can perform functions such as time display, timing, time announcement, message notification, motion detection, heart rate monitoring, and blood oxygen level detection. The strap 20 can be wrapped around the user's wrist, ankle, or upper arm to wear the main body 10 on the user's body.

[0047] The embodiments of this application do not limit the shape of the device body 10. For example, the device body 10 can be circular, elliptical, rectangular or approximately rectangular.

[0048] Please combine Figure 1 and Figure 2 The wearable electronic device 1 also includes earphones 30, which can be stored on the device body 10. For example, the device body 10 may have a storage slot that matches the shape and size of the earphones 30, in which the earphones 30 can be stored. In an example where the device body 10 is circular, the earphones 30 can be stored on the outer edge of the device body 10 in the circumferential direction.

[0049] The device may include one earphone 30, which can be worn on either the user's left or right ear. Alternatively, two earphones 30 may be provided, for example, the earphone 30 may include a first earphone 30a and a second earphone 30b, one of which can be worn on the user's left ear and the other on the user's right ear. The first earphone 30a and the second earphone 30b may be symmetrically housed on both sides of the device body 10, and the center of symmetry of the first earphone 30a and the second earphone 30b may coincide with the geometric center of the device body 10.

[0050] Please refer to Figure 2 and Figure 3 This application provides an earphone 30. The earphone 30 includes a sound-emitting part 100, a first clamping part 200, and a second clamping part 300 connected to each other. For example, the first end 210 of the first clamping part can be connected to the sound-emitting part 100, the second end 220 of the first clamping part can be connected to the first end 310 of the second clamping part, and the second end 320 of the second clamping part can be a free end. Figure 4 and Figure 5 As shown, the first clamping part 200 and the second clamping part 300 can clamp onto the user's auricle to wear the earphone 30 in the user's ear 2. At this time, at least a portion of the sound-emitting part 100 can enter the user's ear canal and be used to play audio. The first clamping part 200 and the sound-emitting part 100 are located on the front side of the user's ear 2, and the second clamping part 300 is located on the back side of the user's ear 2. Here, Figure 4 and Figure 5 The grid lines in the image are only used to indicate human body structures such as the user's ear.

[0051] like Figure 6 As shown, the sound-producing part 100 is a solid of revolution. Here, "solid of revolution" can be understood as a three-dimensional object formed by rotating a planar figure around a rotation axis. For example, the sound-producing part 100 can be spherical, frustum-shaped, cylindrical, or approximately cylindrical.

[0052] In an example where the sound-emitting part 100 is cylindrical or approximately cylindrical, the sound-emitting part 100 has a first end face 110 and a second end face 120 disposed opposite each other along its own axis of rotation. A circumferential sidewall 130 of the sound-emitting part 100 is connected between the first end face 110 and the second end face 120, and a first end 210 of the first clamping part is connected to the circumferential sidewall 130 of the sound-emitting part 100. In a direction parallel to the axis of rotation of the sound-emitting part 100 (hereinafter referred to as the "axis of rotation"), the second end face 120 is closer to the second end 220 of the first clamping part than the first end face 110. When the earphone 30 is worn on the user's ear 2, the second end face 120 of the sound-emitting part 100 faces into the user's ear canal, and the first end face 110 of the sound-emitting part 100 faces outward. Since the sound-emitting part 100 is cylindrical or nearly cylindrical, the shape of the end of the sound-emitting part 100 near the second end face 120 can be adapted to the shape of the user's ear canal, so that the earphone 30 can be worn more securely in the user's ear 2.

[0053] In one embodiment, please refer to Figure 7 The sound-emitting part 100 is provided with an anti-slip groove 140, which surrounds the circumferential sidewall 130 of the sound-emitting part 100. Furthermore, the anti-slip groove 140 is closer to the first end face 110 than the second end face 120. Therefore, the anti-slip groove 140 can prevent the sound-emitting part 100 from sliding between the user's fingers, making it easier for the user to pick up the earphone 30.

[0054] In one implementation, please combine Figure 7 and Figure 8 The sound-emitting part 100 is provided with a first decorative cover 151, and a first end face 110 can be provided on the first decorative cover 151. An anti-slip groove 140 can be formed between the first decorative cover 151 and the sound-emitting part 100. In one example, a second decorative cover 152 can also be provided on the first decorative cover 151. Both the first decorative cover 151 and the second decorative cover 152 can be used to enhance the visual effect of the headphones 30.

[0055] Please refer to Figure 8 The earphone 30 includes a housing 400, which is used to form a sound-emitting part 100, a first clamping part 200 and a second clamping part 300.

[0056] In some implementations, the housing 400 may include a first housing 410 and a second housing 420 connected to each other, the first housing 410 and the second housing 420 together forming the sound-emitting part 100 and the first clamping part 200, and the second end face 120 may be provided on the second housing 420. For example, the first housing 410 and the second housing 420 may be connected to each other by at least one of the following methods: adhesive, snap-fit, or plug-in.

[0057] The housing 400 may further include a third housing 430 and a fourth housing 440 connected to each other, the third housing 430 and the fourth housing 440 together forming a second clamping portion 300 and connected to the first housing 410 and the second housing 420. For example, the third housing 430 and the fourth housing 440 may be connected to each other by at least one of the following methods: adhesive, snap-fit, or plug-in.

[0058] Please combine Figure 8 and Figure 9 The earphone 30 includes a first circuit board 510, a speaker unit 520, and an antenna unit 530. A controller 511 is mounted on the first circuit board 510. The antenna unit 530 is electrically connected to the first circuit board 510. The earphone 30 can establish a communication connection with the device body 10 through the antenna unit 530 and the controller 511, or it can also establish a communication connection with at least one external device such as a mobile phone, computer, or smartwatch to receive digital audio signals from the device body 10 or the external device. For example, the earphone 30 can establish a Bluetooth connection or a Near Field Communication (NFC) connection with at least one of the device body 10 or the external device through the antenna unit 530 and the controller 511.

[0059] The speaker unit 520 is electrically connected to the first circuit board 510. The controller 511 can convert digital audio signals received from the device body 10 or external devices into analog signals and transmit the analog signals to the speaker unit 520. The speaker unit 520 is used to receive analog signals and convert them into audio for output. Accordingly, the earphone 30 in this embodiment is a Bluetooth earphone. For example, the earphone 30 in this embodiment can be a true wireless stereo (TWS) earphone.

[0060] In some implementations, the first circuit board 510 may be at least one of a printed circuit board (PCB) or a rigid-flex board, and the first circuit board 510 may be disposed between the first housing 410 and the second housing 420. For example, at least a portion of the first circuit board 510 may be located within the sound-emitting part 100, and at least a portion of the first circuit board 510 may be located within the first clamping part 200.

[0061] In one example, at least a portion of the first circuit board 510 located within the sound-emitting section 100 may be bonded to the first housing 410 by foam adhesive 512, for example, the foam adhesive 512 may be a printed circuit board assembly (PCBA) foam adhesive. In other examples, at least a portion of the first circuit board 510 located within the sound-emitting section 100 may also be mounted to the first housing 410 by at least one of the following methods: snap-fit ​​or bolt connection.

[0062] The earphone 30 also includes a first bracket 540 located within the first clamping portion 200. The first bracket 540 can be connected to at least one of the first housing 410 and the second housing 420. At least a portion of the first circuit board 510 located within the first clamping portion 200 can be disposed on the first bracket 540 and mounted to the first housing 410 or the second housing 420 via the first bracket 540. Of course, in other examples, at least a portion of the first circuit board 510 located within the first clamping portion 200 can also be mounted to the first housing 410 or the second housing 420 by at least one of the following methods: adhesive, snap-fit, or bolt connection.

[0063] In some implementations, the controller 511 may include at least one of a central processing unit (CPU), a system-on-chip (SOC), an application-specific integrated circuit (ASIC), or a digital signal processor (DSP). The controller 511 may be located on at least a portion of the first circuit board 510 within the first clamping part 200; alternatively, the controller 511 may be located on at least a portion of the first circuit board 510 within the sound-emitting part 100.

[0064] In some implementations, the antenna unit 530 may include at least one of a flexible printed circuit (FPS) antenna or a laser-direct structuring (LDS) antenna. The antenna unit 530 may be disposed within the first clamping portion 200, and may be mounted on the first housing 410 or the second housing 420 via the first bracket 540, or may be mounted on the first housing 410 or the second housing 420 via at least one of other methods such as adhesive bonding or snap-fitting.

[0065] In one example, the first circuit board 510 is provided with a first electrical connection portion 513, which is connected to the antenna unit 530 to electrically connect the antenna unit 530 to the first circuit board 510 and the controller 511. Exemplarily, the first electrical connection portion 513 may include a Pogo Pin connector, or the first electrical connection portion 513 may also include at least one of the following: a flexible circuit board or a wire.

[0066] In some implementations, the speaker unit 520 may include a dynamic driver, and correspondingly, the earphone 30 may be a dynamic driver earphone; in another example, the speaker unit 520 may include a balanced armature driver, and correspondingly, the earphone 30 may be a balanced armature earphone; in yet another example, the speaker unit 520 may also include a piezoelectric driver, and correspondingly, the earphone 30 may be a piezoelectric earphone. In the above examples, there may be multiple speaker units 520, and each speaker unit 520 may be a dynamic driver, a balanced armature driver, or a piezoelectric driver. For example, in an example where the speaker unit 520 includes at least one dynamic driver and at least one balanced armature driver, the earphone 30 may be a hybrid driver earphone.

[0067] In one example, the earphone 30 further includes a second circuit board 550. The first circuit board 510 is further provided with a second electrical connection portion 514, which is connected to the second circuit board 550. The speaker unit 520 is connected to the second circuit board 550 and electrically connected to the first circuit board 510 via the second circuit board 550 and the second electrical connection portion 514. The second circuit board 550 may include at least one of a flexible circuit board and a rigid-flex board, and the second electrical connection portion 514 may include at least one of a pogo pin connector or a metal contact. In other examples, the speaker unit 520 may also be electrically connected to the first circuit board 510 via at least one of a wire or solder.

[0068] The sound-emitting part 100 is provided with a sound outlet 160, which penetrates the outer shell 400 and is correspondingly disposed with respect to the speaker unit 520. The speaker can transmit sound to the outside of the sound-emitting part 100 through the sound outlet 160. This application embodiment does not limit the number or shape of the sound outlet 160. The sound outlet 160 can be disposed on the circumferential sidewall 130 of the sound-emitting part 100, and in the first direction x perpendicular to the axis of rotation, the sound outlet 160 and the first clamping part 200 can be respectively disposed on both sides of the sound-emitting part 100. The sound outlet 160 can be disposed on at least one of the first shell 410 and the second shell 420; for example, the sound outlet 160 can be disposed on the second shell 420.

[0069] In one embodiment, the sound outlet 160 is closer to the second end face 120 than the first end face 110. With this arrangement, when the earphone 30 is worn on the user's ear 2, the sound outlet 160 can face into the user's ear canal, improving the sound reception effect.

[0070] In one example, please refer to Figure 7 In an example where there are multiple sound holes 160, the multiple sound holes 160 can be symmetrically arranged on both sides of the sound-emitting part 100, and the axis of symmetry of each sound hole 160 can be parallel to the axis of rotation of the sound-emitting part 100. Thus, as... Figure 4 As shown, when the earphone 30 is worn in either the user's left or right ear, the sound outlet 160 can face into the user's ear canal.

[0071] In some implementations, a dust cover 170 is provided on the sound-emitting part 100, and a sound outlet 160 can be provided on the dust cover 170. The sound outlet 160 is relatively small, thus the dust cover 170 can prevent dust and other contaminants from entering the sound-emitting part 100. The material used to make the dust cover 170 can include at least one of plastic, metal, or glass, and the dust cover 170 can be installed on the second housing 420 by at least one of ultrasonic bonding, adhesive bonding, or snap-fitting.

[0072] The outer casing 400 may be provided with a sound vent 411, which penetrates the outer casing 400 and is used to regulate the air pressure inside the outer casing 400. This application embodiment does not limit the number or shape of the sound vent 411. For example, the sound vent 411 may be elongated, and may extend along the extending direction of the first clamping portion 200 and the second clamping portion 300. This increases the area of ​​the sound vent 411 and makes its shape compatible with the shape of the earphone 30, improving the visual effect of the earphone 30. In one example, the area of ​​the sound vent 411 is not less than 3.36 mm². 2 This can improve the sound quality of the headphones by 30.

[0073] The sound vent 411 can be provided on at least one of the sound-emitting part 100 or the first clamping part 200, and the sound vent 411 can be provided on at least one of the first housing 410 or the second housing 420. For example, the sound vent 411 can be provided on at least a portion of the first housing 410 surrounding the first clamping part 200. As a result, the distance between the sound vent 411 and the speaker unit 520 is small, and there are fewer other components located between the sound vent 411 and the speaker unit 520 in the headphone 30, which is beneficial to improving the sound effect of the headphone 30.

[0074] A first dustproof mesh 451 is provided on the inner wall of the outer casing 400. The first dustproof mesh 451 is used to cover the sound leakage hole 411 to prevent water or dust from entering the earphone 30, thereby achieving a waterproof and dustproof effect. At the same time, sound can be transmitted between the inside and outside of the earphone 30 through the first dustproof mesh 451. For example, the material used to make the first dustproof mesh 451 may include at least one of nylon, polyester resin (Polyethylene terephthalate, abbreviated as PET), or metal. The first dustproof mesh 451 can be installed on the outer casing 400 by at least one of the following methods: adhesive or snap-fit.

[0075] Please continue to refer to Figure 9 The headset 30 also includes a microphone unit 560, which is electrically connected to the controller 511. The headset 30 has a microphone hole corresponding to the microphone unit 560. The microphone unit 560 can collect human voice through the microphone hole to enable call functionality in conjunction with the controller 511 and the antenna unit 530. Alternatively, the microphone unit 560 can also collect ambient sound through the microphone hole to enable noise reduction functionality in conjunction with the controller 511.

[0076] For example, the microphone unit 560 may include a first microphone 561, which is located within the sound-emitting section 100 and may be disposed on at least a portion of the first circuit board 510 within the sound-emitting section 100 to enable electrical connection with the controller 511. Correspondingly, as... Figure 11 As shown, the microphone hole may include a first microphone hole 1511, which may be disposed on the first decorative cover 151 and located on the first end face 110. The first microphone hole 1511 is correspondingly disposed with the first microphone 561. In one example, the first microphone hole 1511 may be covered under the second decorative cover 152.

[0077] The microphone unit 560 may further include a second microphone 562, which is located within the first clamping portion 200 and may be disposed on at least a portion of the first circuit board 510 within the first clamping portion 200 to enable electrical connection with the controller 511. Correspondingly, the microphone hole may include a second microphone hole 412, which is disposed on at least a portion of the housing 400 surrounding the first clamping portion 200 and corresponds to the second microphone 562. For example, the second microphone hole 412 may be disposed on the first housing 410.

[0078] Both the first microphone 561 and the second microphone 562 can be used to collect human voices or ambient sounds. For example, the first microphone 561 can be used to collect human voices, and the second microphone 562 can be used to collect ambient sounds.

[0079] Please combine Figure 4 and Figure 11In some implementations, the first microphone hole 1511 may be located at the end of the first end face 110 away from the first clamping part 200, and the second microphone hole 412 may be located at the end of the first clamping part 200 away from the sound-emitting part 100. Correspondingly, the first microphone 561 is located inside the sound-emitting part 100 on the side away from the first clamping part 200, and the second microphone 562 is located inside the first clamping part 200 on the side away from the sound-emitting part 100.

[0080] With the above configuration, the distance between the first microphone hole 1511 and the second microphone hole 412 is relatively large. When the user wears the headset 30, the first microphone hole 1511 is closer to the user's mouth than the second microphone hole 412, which facilitates the first microphone 561 in collecting human voice and improves call quality. The second microphone hole 412 is farther from the user's mouth than the first microphone hole 1511, which facilitates the second microphone 562 in collecting ambient sound and improves noise reduction. At the same time, both the first microphone hole 1511 and the second microphone hole 412 are far from the vent hole 411, which helps reduce the impact of sound transmitted from the speaker unit 520 to the outside of the headset 30 through the vent hole 411 on the first microphone 561 and the second microphone 562, thus improving call quality and noise reduction.

[0081] In some implementations, the orientation of the first microphone hole 1511 and the orientation of the second microphone hole 412 form an angle. That is, the first microphone hole 1511 and the second microphone hole 412 face different directions. This is beneficial for the microphone 562 to collect ambient sound and for improving noise reduction. In some examples, the first microphone hole 1511 and the vent hole 411 face different directions, and the second microphone hole 412 and the vent hole 411 face different directions. This is beneficial for reducing the impact of sound transmitted from the speaker unit 520 through the vent hole 411 to the earphone 30 on the first microphone 561 and the second microphone 562, thus improving call quality and noise reduction.

[0082] In the above example, a second dustproof mesh 452 and a third dustproof mesh 453 may also be provided on the inner wall of the outer casing 400. The second dustproof mesh 452 and the third dustproof mesh 453 can respectively cover the first sound receiving hole 1511 and the second sound receiving hole 412 to prevent water or dust from entering the earphone 30, thereby achieving a waterproof and dustproof effect. At the same time, sound can be transmitted inside and outside the earphone 30 through at least one of the second dustproof mesh 452 and the third dustproof mesh 453. For example, the materials used to make the second dustproof mesh 452 and the third dustproof mesh 453 may include at least one of materials such as nylon, polyester resin, or metal. The second dustproof mesh 452 and the third dustproof mesh 453 can be installed on the outer casing 400 by at least one of the following methods: adhesive or snap-fit.

[0083] The earphone 30 also includes a battery 570, which is electrically connected to the first circuit board 510 and supplies power to the controller 511, speaker unit 520, or microphone unit 560 to ensure the normal operation of the earphone 30. The battery 570 is fixedly connected to the housing 400 and is located within the sound-emitting part 100. For example, the earphone 30 may also include a second bracket 580, which is located within the sound-emitting part 100 and connected to at least one of the first housing 410 and the second housing 420. The battery 570 may be disposed on the second bracket 580 and mounted to the housing 400 via the second bracket 580. The second bracket 580 may be mounted to the housing 400 by at least one of the following methods: adhesive bonding or snap-fitting. The battery 570 may also be mounted to the second bracket 580 by at least one of the following methods: adhesive bonding or snap-fitting.

[0084] In some implementations, the material used to make the second support 580 may include at least one of materials such as plastic or metal. For example, the material used to make the second support 580 may include at least one magnetic material such as iron, cobalt, or nickel, thereby allowing the second support 580 to attract the battery 570, so that the battery 570 can be securely mounted on the second support 580.

[0085] In some implementations, the battery 570 can be electrically connected to the first circuit board 510 via the second circuit board 550 and the second electrical connection portion 514. In other implementations, the battery 570 can also be electrically connected to the first circuit board 510 via at least one of the following: a wire or solder.

[0086] In the above example, at least a portion of the second electrical connection portion 514 can penetrate the housing 400 and be exposed outside the earphone 30. When the earphone 30 is stored on the device body 10, the device body 10 can be electrically connected to the second electrical connection portion 514 and charge the battery 570 through the second electrical connection portion 514.

[0087] The earphone 30 also includes a first magnetic adsorption element 591 and a second magnetic adsorption element 592. The materials used to make the first magnetic adsorption element 591 and the second magnetic adsorption element 592 can both include at least one magnetic material such as iron, cobalt, or nickel. Both the first magnetic adsorption element 591 and the second magnetic adsorption element 592 can be magnetically connected to a magnet within the device body 10 to securely house the earphone 30 within the device body 10. This also allows the earphone 30 to be easily removed from the device body 10. The first magnetic adsorption element 591 can be located within the sound-emitting part 100, and the second magnetic adsorption element 592 can be located within the second clamping part 300.

[0088] Please combine Figure 6 and Figure 10The second clamping part 300 is rotatably connected to the first clamping part 200. For example, the rotation axis (hereinafter referred to as "rotation axis") of the first clamping part 200 and the second clamping part 300 can be perpendicular to the rotation axis of the sound-emitting part 100.

[0089] The second clamping part 300 is used to rotate relative to the first clamping part 200 to clamp the user's ear 2 between the first clamping part 200 and the second clamping part 300, thereby allowing the earphone 30 to be worn on the user's ear 2. At this time, as Figure 10 As shown, the earphone 30 can be in a wearing state. The second clamping part 300 is also used to rotate relative to the first clamping part 200 so that the earphone 30 can be stored on the device body 10. At this time, as Figure 6 As shown, the earphone 30 can be in a stowed state.

[0090] During the rotation of the second clamping part 300 relative to the first clamping part 200, the earphone 30 switches between a stored state and a wearing state. Based on the above configuration, the first clamping part 200 and the second clamping part 300 can adapt to the ears 2 of different users. Users can rotate the second clamping part 300 to any position according to the shape and size of the ear 2 and their wearing needs, thereby improving the wearing effect and user experience.

[0091] In some implementation methods, please combine Figure 8 and Figure 9 The first clamping part 200 can be rotatably connected to the second clamping part 300 via a pivot 610. For example, the earphone 30 may include a first connector 620, a pivot 610, and a second connector 630. The first clamping part 200 is provided with a connecting groove 421, for example, the connecting groove 421 may be provided on the second housing 420, and the first connector 620 is located within the connecting groove 421. At least a portion of the pivot 610 is located within the connecting groove 421 and connected to the first connector 620. The first connector 620 is capable of elastic deformation, and the material used to make the first connector 620 may include at least one of materials capable of elastic deformation, such as plastic, metal, or rubber. Thus, the first connector 620 can undergo elastic deformation, allowing the pivot 610 to rotate relative to the first clamping part 200.

[0092] The second connector 630 is disposed within the second clamping portion 300. For example, the second connector 630 may be disposed on at least one of the third housing 430 or the fourth housing 440. The second connector 630 is fixedly connected to the rotating shaft 610, thereby causing the second clamping portion 300 to rotate relative to the first clamping portion 200 when the rotating shaft 610 rotates relative to the first clamping portion 200. The material used to make the second connector 630 may include at least one of materials such as plastic or metal, and the second connector 630 may be manufactured using a powder metallurgy process.

[0093] For example, during the transition of the earphone 30 from a stored state to a worn state, while the second clamping part 300 rotates relative to the first clamping part 200, the first connector 620 can accumulate elastic potential energy. During the transition of the earphone 30 from a worn state to a stored state, the first connector 620 can release elastic potential energy and generate torque to drive the rotating shaft 610 to rotate, thereby causing the second clamping part 300 to rotate relative to the first clamping part 200.

[0094] In the example where the first clamping part 200 and the second clamping part 300 are rotatably connected by a pivot, the pivot can provide frictional damping between the first clamping part 200 and the second clamping part 300, allowing the second clamping part 300 to rotate to any position and then be fixed relative to the first clamping part 200. Therefore, the second clamping part 300 can rotate relatively stably relative to the first clamping part 200, making it easier for the user to control the rotation speed and angle of the second clamping part 300. Furthermore, the second clamping part 300 can be held in a certain position relative to the first clamping part 200 without easily loosening, allowing the earphone 30 to be worn more securely on the user's ear 2.

[0095] In some other implementations, the first clamping part 200 may also be rotatably connected to the second clamping part 300 via a hinge.

[0096] The earphone 30 also includes a human body sensing unit 700, which is located inside the earphone housing 400 and contacts the inner wall of the housing 400. The human body sensing unit 700 is configured to generate an electrical signal based on changes in capacitance on the outer surface of the housing 400. For example, when a user touches the housing 400, a change in capacitance occurs between the housing 400 and the human body sensing unit 700, and the human body sensing unit 700 can generate an electrical signal. The human body sensing unit 700 is electrically connected to the first circuit board 510 and can transmit the electrical signal to the controller 511 to detect whether a user is touching the earphone 30.

[0097] The human body sensing unit 700 may include a flexible circuit board. For example, the human body sensing unit 700 may include at least a portion of the second circuit board 550. Alternatively, the human body sensing unit 700 may also include a capacitive sensor, etc.

[0098] In one embodiment, there are multiple human body sensing units 700, which can be respectively disposed in the sound-emitting part 100 and the first clamping part 200, and each connected to at least one of the first housing 410 or the second housing 420. Thus, the human body sensing unit 700 can accurately detect whether the user is wearing the headphones 30.

[0099] In some implementations, the human body sensing unit 700 may include a first sensing unit, a second sensing unit, a third sensing unit, and a fourth sensing unit, and each of the first sensing unit, the second sensing unit, the third sensing unit, and the fourth sensing unit may include at least a portion of the second circuit board 550.

[0100] For example, the first sensing unit may include at least a portion of the second circuit board 550 within range A. The first sensing unit may be disposed within the first clamping portion 200 and may contact the inner wall of the first clamping portion 200. Thus, the first sensing unit can detect whether the user's auricle is in contact with the first clamping portion 200 to detect whether the user is wearing the earphone 30.

[0101] The second sensing unit may include at least a portion of the second circuit board 550 within range B. The second sensing unit may be disposed within the sound-emitting part 100 and may contact the circumferential sidewall 130, the second end face 120, and the inner wall corresponding to the connection between the circumferential sidewall 130 and the second end face 120 of the sound-emitting part 100. Thus, the second sensing unit can detect whether the user's cochlea is in contact with the sound-emitting part 100, thereby detecting whether the user is wearing the headphones 30.

[0102] The third sensing unit may include at least a portion of the second circuit board 550 within range C. The third sensing unit may be disposed within the sound-emitting part 100 and may contact the inner wall corresponding to the second end face 120 of the sound-emitting part 100. Thus, the third sensing unit can detect whether the user's cochlea is in contact with the sound-emitting part 100, thereby detecting whether the user is wearing the headphones 30.

[0103] The fourth sensing unit may include at least a portion of the second circuit board 550 within range D. The fourth sensing unit may be annular, disposed within the sound-emitting part 100, and may contact the inner wall corresponding to the circumferential sidewall 130 of the sound-emitting part 100. Thus, the fourth sensing unit can detect whether the user's cochlea is in contact with the sound-emitting part 100, thereby detecting whether the user is wearing the headphones 30.

[0104] In the above example, both the first clamping portion 200 and the second clamping portion 300 can be arc-shaped, that is, both the first clamping portion 200 and the second clamping portion 300 can extend along the arc of a perfect circle. Furthermore, the radius of the circle containing the first clamping portion 200 can be equal to the radius of the circle containing the second clamping portion 300. Therefore, when the first clamping portion 200 and the second clamping portion 300 are rotated relative to each other to a wearing state, the shape of the gap between the first clamping portion 200 and the second clamping portion 300 can be adapted to the shape of the user's ear 2, and both the first clamping portion 200 and the second clamping portion 300 can fit snugly against the user's ear 2, improving the user experience.

[0105] In some implementations, the second clamping part 300 is provided with an arc surface 330, which is adapted to the contour of the ear part 2. Therefore, when the first clamping part 200 and the second clamping part 300 are rotated relative to each other to a wearing position, the shape of the gap between the first clamping part 200 and the second clamping part 300 can be adapted to the shape of the user's ear 2, and the second clamping part 300 can fit snugly against the user's ear 2, improving the user experience.

[0106] In one example, please refer to Figure 6 In a direction parallel to the axis of rotation, the distance between the connection point of the sound-emitting part 100 and the first clamping part 200 and the first end face 110 of the sound-emitting part 100 is L1, and the distance between the connection point of the first clamping part 200 and the second clamping part 300 and the first end face 110 of the sound-emitting part 100 is L2. The ratio of L1 to L2 can be in the range of 2 to 1. For example, the ratio of L1 to L2 can be 4.4 / 3.9. Here, "the connection point of the first clamping part 200 and the second clamping part 300" can be understood as the position where the second end 220 of the first clamping part and the first end 310 of the second clamping part contact each other when the earphone 30 is in the retracted state.

[0107] Therefore, the distance between the second clamping part 300 and the sound-emitting part 100 is small. During the transition of the earphone 30 from the stored state to the wearing state, the rotation angle of the second clamping part 300 is small, making it easier for the user to wear the earphone 30 on the ear 2 and improving the user experience. Furthermore, it facilitates a close fit between the first clamping part 200 and the second clamping part 300 and the user's ear 2, allowing the first clamping part 200 and the second clamping part 300 to be securely clamped on the user's ear 2. Of course, the ratio of L1 to L2 is not limited to 4.4 / 3.9. In other embodiments, the ratio of L1 to L2 can also be other numbers.

[0108] In one embodiment, when the first clamping part 200 and the second clamping part 300 rotate relative to each other to a retracted state, the first clamping part 200 and the second clamping part 300 together form a partial arc of a circle. That is, the center of the circle containing the first clamping part 200 and the center of the circle containing the second clamping part 300 can coincide. Thus, in the example where the device body 10 is circular, the earphone 30 retracted on the device body 10 can match the shape of the device body 10, improving the visual effect of the wearable electronic device 1.

[0109] In one example, when the first clamping part 200 and the second clamping part 300 rotate relative to each other to a retracted state, the line connecting the connection point of the first clamping part 200 and the second clamping part 300 to the center of the circle containing the first clamping part 200 is a first straight line. The angle α between the first straight line and the axis of rotation can be in the range of 30° to 90°. For example, the angle α can be 64.6°. Of course, the angle α can also be other angles and is not limited to 64.6°.

[0110] With the above settings, when the second clamping part 300 is rotated relative to the first clamping part 200 to the wearing state, the first clamping part 200 and the second clamping part 300 can be clamped more securely to the user's ear 2.

[0111] In one example, the line connecting the rotational connection point of the first clamping part 200 and the second clamping part 300 to the center of the circle containing the first clamping part 200 is a second straight line. The angle β between the second straight line and the axis of rotation can be in the range of 30° to 90°. For example, the angle β can be 71°. Of course, the angle between the second straight line and the axis of rotation can also be other angles and is not limited to 71°.

[0112] Here, "the rotatable connection between the first clamping part 200 and the second clamping part 300" can be understood as the location of the rotation axis of the first clamping part 200 and the second clamping part 300. For example, in the example where the first clamping part 200 and the second clamping part 300 are rotatably connected by a pivot 610, "the rotatable connection between the first clamping part 200 and the second clamping part 300" can be understood as the location of the pivot 610. For example, as... Figure 6 As shown, the rotatable connection between the first clamping part 200 and the second clamping part 300 can be located at any position within range a.

[0113] With the above settings, when the second clamping part 300 is rotated relative to the first clamping part 200 to the wearing state, the first clamping part 200 and the second clamping part 300 can be clamped more securely to the user's ear 2.

[0114] In the example above, the included angle β can be greater than or equal to the included angle α. For example, the difference between included angle β and included angle α can be in the range of 20° to 0°.

[0115] In one embodiment, please refer to Figure 10When the first clamping part 200 and the second clamping part 300 are rotated relative to each other to the wearing state, both the first clamping part 200 and the second clamping part 300 are located on the same side of the rotation axis, and in a first direction x perpendicular to the rotation axis, there is a distance L3 between the second clamping part 300 and the rotation axis. For example, the distance L3 between the second clamping part 300 and the rotation axis can be between 2mm and 4mm. Therefore, when the user wears the earphone 30, the second clamping part 300 is farther from the root of the user's ear 2, which avoids the second clamping part 300 pressing against the root of the user's ear 2, thus improving the user experience.

[0116] In one embodiment, when the first clamping part 200 and the second clamping part 300 are rotated relative to each other to the wearing state, the distance L4 between the second end 320 of the second clamping part and the sound-emitting part 100 can be greater than or equal to 2mm. Therefore, the earphone 30 can be adapted to the size of the user's ear 2 and can be worn more securely in the user's ear 2.

[0117] In one embodiment, the arc length of the first clamping portion 200 is greater than the arc length of the second clamping portion 300. Therefore, when the user wears the earphone 30, the second clamping portion 300 can be prevented from pressing against the base of the user's ear 2, thus improving the user experience.

[0118] In one embodiment, the distance between the rotation axes of the first clamping portion 200 and the second clamping portion 300 and the first end 210 of the first clamping portion is a first distance La, and the distance between the rotation axes of the first clamping portion 200 and the second clamping portion 300 and the second end 320 of the second clamping portion is a second distance Lb, wherein the first distance La is greater than the second distance Lb. That is, compared to the first end of the first clamping portion 200, the rotation axes of the first clamping portion 200 and the second clamping portion 300 are closer to the second end 320 of the second clamping portion. Therefore, when the user wears the earphone 30, the second clamping portion 300 can be prevented from pressing against the root of the user's ear 2, thus improving the user experience.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or as many of the technical features as possible; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
